JOHN ANGELL, OF ST. LOUIS, MISSOURI.

STEAM-SEPARATOR.

SPECIFICATION forming part of Letters Patent N 0. 710,655, dated October 7, 1902.

Application filed April 24, 1901. Renewed February 3, 1902. Serial No. 92,314. (No model.)

To all whom it Hui/y concern:

Be it known that I, JOHN ANGELL, a citizen of the United States of America, and a resident of St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Steam-Separators, of which the following is a specification.

This invention relates to that type of separators for removing oil, water of condensation, dzc, from steam and in which the steam is given a circuitous course through the apparatus to assist in such separation.

The present improvement has for its object to provide a simple and effective formation and arrangement of parts adapted to effect and maintain an efficient separation of the water and oil from the passing steam, all as will hereinafter more fully appear and be more particularly pointed out in the claims. I attain such object by the construction and arrangement of parts illustrated in the accompanying drawings, in which- Figure 1 is a central vertical sectional elevation of a steam-separator embodying the present invention; Fig. 2, a plan view of the same with the upper head or closure-cap removed.

Similar numerals of reference indicate like parts in both views.

Referring to the drawings, 1 represents the main separator-casing, composed of a cylind rical body portion and top and bottom heads or closure-caps 2 and 3 of a substantially counterpart construction and each in my preferred construction, as shown in full lines in Fig. l of the drawings, provided with a central orifice and attaching margins, to which nular receiving-chamber 9 for the Water, &o., of entrainment separated from the steam in its passage through the present apparatus.

It is evident that the neck or extension 8 can be modified so as to curve laterally in the manner indicated in dotted lines in Fig.

1, in situations in which the steam-separator is required to be applied to an angular arrangement of such steam pipe or main.

10 is a drain-pipe connected to the lower end of the annular receiving-chamber 9 for the removal at any required intervals of the oil, water, &c., accumulated therein.

11 is a cylindrical casing supported axially within the upper portion of the separatorcasing by means of radial fins 12, fitting in recesses in the top of the main cylindrical section of the separator-casing, as illustrated in Figs. 1 and 2, and having a diametersomewhat less than the internal diameter of such separator-casing, so as to leave an annular passage between the parts, as shown in Figs. 1 and 2. Such casing is formed with an open flanged top and with a closed bottom, the central portion 13 of which is of acone form, the marginal portion of which is curved upwardly to meet the cylindrical wall of the casing 11, while the central portion 12 is of a cone form, such construction being adapted to attain a ready shedding or fiow of the water, &c., toward the outlet therefor from such cas ing.

14: represents outlet-pipes, one or more in number, connecting with the lower end of the casing 11 and extending to near the bottom of the annular receiving-chamber 9.

15 is a grid or break having a marginal flange, by means of which it is attached to the open flanged top of the casing 11. Such grid is also provided with an annular depending rim 16, that is adapted to prevent in a very efficient manner the usual tendency of the oil and moisture upon the inner Wall of the casing to creep in the same direction with the steam as it passes back from the interior of the casing 11 into the annular passage surrounding the same. In the present invention the main central portion of the grid 11, will have a sunken form, and composed of a series of circular rings 17, arranged and held in separated relation by radial bars 18, all preferably cast together in one integral piece, as

shown, and with a view to offer the least amount of resistance to the passage of the steam, &c., through the grid in the initialentrance thereof into the separator and, in addition, efiect an efficient division or dissemination of such steam, &c., the said rings 17 and bars 18 will have a triangular shape in cross-section, with their apices in the direction of the incoming steam, &c. In the present construction the bottom of the casing 11 will have adjacent relation to the grid or break 15, as shown in Fig. 1, so asto constitute an impact Wall or surface for the steam, 850., passing down through such grid, so as to insure a very perfect separation of the oil, water, &c., of entrainment carried by the steam, in that the particles of the same in the described disseminated condition will as they impact against the bottom of the casing 11 readily lose their momentum and adhere to such bottom, to be subsequently carried by gravity down into the annular receiving-chamber 9 through the drain-pipes 10.

No claim is made in the present application to the broad feature of a reticulated grid in combination with an impact-wall arranged in adjacent relation thereto, as the same is involved in the subject-matter of a companion application filed April 24, 1901, Serial No. 57,162.

Having thus fully described my said invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A steam-separator, comprising in combination a vertically-arranged main casing, an inner casing having a bottom and supported centrally in the upper portion of the main casing by radial ribs, to leave an annular passage at its sides, a reticulated grid or break at the top of said inner casing, a centrallyarranged inlet-neck at the top of the main casing, an outlet-neck extending upwardly into the main casing with its opening arranged axially and in adjacent relation to the bottom of the inner casing, and a drain-pipe extending from the bottom of the inner casing to the bottom portion of the main casing, substantially as set forth.

2. A steam-separator, comprising in combination, a vertically-arranged. main casing, an inner casing having a bottom and arranged centrally in the upper portion of the main casing to leave an annular passage at its sides, a reticulated grid or break at the top of said inner casing, a centrally-arranged inlet-neck at the top of the main casing, an outlet-neck extending axially up into the main casing with its opening in adjacent relation to the bottom of the inner casing, and a drain-pipe extending from the bottom of the inner casing to the bottom portion of the main casing, substantially as set forth.

3. A steam-separator, comprising in combination, a vertically-arranged cylindrical casing having upper and lower removable heads, an inner casing havingabottom and arranged centrally in the upper portion of the main casing to leave an annular passage at its sides, a reticulated grid or break at the top of said inner casing, a centrally-arranged inlet-neck at the top of the main casing, an outlet-neck extending upwardly into the main casing with its opening arranged axially and in adjacent relation to the bottom of the inner casing, and a drain-pipe extending from the bottom of the inner casing to the bottom portion of the main casing, substantially as set forth.
